POSIX and GNU instead of separate include files like time_r.h
and timegm.h. This implementation tries out a simpler approach
for replacing decls in standard include files (as compared to
the string module), somewhat as an experiment.
* config/srclist.txt: Comment out mktime.c for now.
* doc/gnulib-tool.texi (Initial import): Don't use time_r as an example
since it doesn't apply any more. Use generic wording instead.
* MODULES.html.sh (Support for systems lacking POSIX:2001): New module
'time'.
* lib/time_.h, m4/time_h.m4, modules/time: New files.
* lib/strptime.h, lib/time_r.h, lib/timegm.h: Remove.
* lib/mktime.c: Include config.h depending on _LIBC, not HAVE_CONFIG_H.
Don't include <sys/types.h>; no longer needed since we assume C89.
* lib/mktime.c: Don't include "time_r.h"; no longer needed.
* lib/strftime.c: Likewise.
* lib/time_r.c: Likewise.
* lib/nanosleep.c (nanosleep): #undef after include files, not before.
* lib/nanosleep.c: Include <time.h> first, to check interface.
* lib/strptime.c: Likewise.
* lib/time_r.c: Likewise.
* lib/timegm.c: Likewise.
* lib/strptime.c: Don't include strptime.h or time_r.h; no longer
needed.
* lib/timegm.c: Don't include timegm.h; no longer needed.
* lib/timespec.h: Don't include <sys/time.h> before <time.h>;
time.h now handles any problems in that area.
(struct timespec, nanosleep): Remove; time.h now arranges for these.
* lib/xnanosleep.c: Don't include timespec.h; no longer needed now
that time.h defines struct timespec.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Check that nanosleep is declared.
Set REPLACE_NANOSLEEP. Don't AC_DEFINE nanosleep; the time module now
handles that.
* m4/strptime.m4 (gl_FUNC_STPRTIME): Set REPLACE_STRPTIME.
* m4/time_r.m4 (gl_TIME_R): Don't define HAVE_TIME_R_POSIX; no longer
needed. Set REPLACE_LOCALTIME.
* m4/timegm.m4 (gl_FUNC_TIMEGM): Set REPLACE_TIMEGM.
* m4/timespec.m4 (gl_CHECK_TYPE_STRUCT_TIMESPEC): Move to time_h.m4.
(gl_TIMESPEC): Don't check for sys/time.h or struct timespec or
nanosleep; time_h.m4 now does that. Don't require
gl_USE_SYSTEM_EXTENSIONS; no longer needed directly, and the time
module handles this now.
* modules/getdate (Depends-on): Remove timespec. Add time.
* modules/nanosleep (Depends-on): Likewise.
* modules/stat-time (Depends-on): Likewise.
* modules/nanosleep (Include): Include time.h, not timespec.h.
* modules/strptime (Files): Remove lib/strptime.h.
(Depends-on): Add extensions, time.
(Include): Include time.h, not strptime.h.
* modules/time_r (Files): Remove lib/time_r.h.
(Depends-on): Add time.
(Include): Include time.h, not time_r.h.
* modules/timegm: Likewise.
* modules/timespec (Description): Now does timespec-related decls
of our own, instead of struct timespec itself.
(Depends-on): Add time; remove extensions.
(Maintainer): Add self.
* modules/utimecmp (Depends-on): Add time; remove timespec.
* modules/utimens (Depends-on): Likewise.
* modules/xnanosleep (Depends-on): Likewise.
module sys_time.
* lib/gethrxtime.c: Include <sys/time.h>, since we can no longer
assume timespec.h defines struct timeval.
* lib/settime.c: Likewise.
* lib/utimens.c: Likewise.
* lib/gettime.c (gettime): Remove test against HAVE_GETTIMEOFDAY,
since we now assume the gettimeofday module.
* lib/tempname.c (__gen_tempname): Likewise.
* lib/gettimeofday.h: Remove.
* lib/gettimeofday.c: Include <sys/time.h> instead of "gettimeofday.h".
Don't include <sys/types.h> and <stdlib.h>; shouldn't be needed.
Include <time.h>, for 'time()'.
(localtime_buffer_addr): Also use this workaround if
TZSET_CLOBBERS_LOCALTIME. Set to a dummy static variable by default,
to simplify the uses. All uses changed.
(localtime, gmtime, tzset, gettimeofday): Reformat slightly so
that #undef is inside {}, and 'const' follows type name consistently.
(tzset): Define replacement only if TZSET_CLOBBERS_LOCALTIME.
(gettimeofday): Do not use the maximum possible value for
tv->tv_usec, since that might break usages other than ls.c.
Instead, we'll leave ls.c alone. This undoes today's patch
by Bruno. Add a compile-time warning for 1s-clock resolution;
we've never observed the problem but might as well keep the
canary.
* lib/nanosleep.c: Include timespec.h first, for interface check.
* lib/nanosleep.c: Include <sys/time.h> unconditionally, since we
now assume the sys_time module.
* lib/tempname.c: Likewise.
* lib/timespec.h: Likewise.
* lib/nanosleep.c: Don't worry about TIME_WITH_SYS_TIME; no longer
needed.
* lib/strftime.c: Likewise.
* lib/timespec.h: Likewise.
* lib/posixtm.c: Include posixtm.h first, for interface check.
Don't worry about TM_IN_SYS_TIME; that's wayyy obsolete.
* lib/posixtm.h: Include stdbool.h and time.h, for proper interface.
* lib/strftime.c: Don't include <sys/types.h>; shouldn't be needed.
* lib/sys_time_.h: New file.
* lib/timespec.h (struct timespec): Use long int, not long.
* m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY):
(gl_FUNC_GETTIMEOFDAY_CLOBBER, gl_PREREQ_GETTIMEOFDAY):
Remove obsolescent call to AC_HEADER_TIME.
* m4/mktime.m4 (AC_FUNC_MKTIME): Likewise.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise.
* m4/strftime.m4 (gl_FUNC_STRFTIME): Likewise.
* m4/timespec.m4 (gl_TIMESPEC, gl_CHECK_TYPE_STRUCT_TIMESPEC):
Likewise.
* m4/tzset.m4 (gl_FUNC_TZSET_CLOBBER): Likewise.
* m4/utimbuf.m4 (gl_CHECK_TYPE_STRUCT_UTIMBUF): Likewise.
* m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY): Move sys/time.h tests
into the sys_time module. Check for gettimeofday just once.
Prefix our variables with gl_, not with ac_ or jm_. Tighten test
for gettimeofday signature to just check the signature. Merely
compile it, since linking doesn't test signature. Improve test for
whether gettimeofday.o is actually needed.
(gl_FUNC_GETTIMEOFDAY_CLOBBER): Renamed from
AC_FUNC_GETTIMEOFDAY_CLOBBER. All uses changed. Use
AC_RUN_IFELSE rather than AC_TRY_RUN. If clobbering, set
and define GETTIMEOFDAY_CLOBBERS_LOCALTIME.
(gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Don't define
GETTIMEOFDAY_CLOBBERS_LOCALTIME; that's gl_FUNC_GETTIMEOFDAY_CLOBBER's
job. Don't define tzset; that's gl_FUNC_TZSET_CLOBBER's job.
* m4/mktime.m4 (AC_FUNC_MKTIME): Just include <time.h> rather
than worrying about sys/time.h.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP):
Don't bother worrying about TIME_WITH_SYS_TIME.
* m4/stat-time.m4 (gl_STAT_TIME): Likewise.
* m4/posixtm.m4 (gl_POSIXTM): Remove obsolescent call to AC_STRUCT_TM.
* m4/sys_time_h.m4: New file.
* m4/tzset.m4 (gl_FUNC_TZSET_CLOBBER): Require gl_HEADER_SYS_TIME_H.
Don't include sys/time.h. Return from main rather than exiting.
Define TZSET_CLOBBERS_LOCALTIME, for consistency with other names;
all uses changed.
* modules/gethrxtime (Depends-on): Add sys_time.
* modules/gettime (Depends-on): Likewise.
* modules/gettimeofday (Depends-on): Likewise.
* modules/nanosleep (Depends-on): Likewise.
* modules/settime (Depends-on): Likewise.
* modules/tempname (Depends-on): Likewise.
* modules/utimens (Depends-on): Likewise.
* modules/gettimeofday (Files): Remove lib/gettimeofday.h.
(Include:) Change back to <sys/time.h>.
(Maintainer:) Add self.
* modules/sys_time: New file.
* modules/tempname (Depends-on): Add gettimeofday.
* tests/test-gettimeofday.c: Include <sys/time.h>
rather than gettimeofday.h.
possible in other modules, but not included here.
* modules/wchar: New module.
* m4/wchar.m4: New file.
* lib/wchar_.h: Likewise.
* modules/mbchar (Depends-on): Depend on wchar, as the first use
of the new module.
* MODULES.html.sh (Extended multibyte and wide character utilities):
New section.
